AI 评阅：DeepSeek Flash 给老师评分项出建议分和评语，老师采纳后生效
- 学生提交时浏览器给每个窗体截图（运行时同一套 FormWindow 在屏幕外渲染），随提交保存 - 自动评分后进入 AI 评阅队列：按书上评价表给老师评分项打建议分、写评语（JSON 输出，服务器再校验、限制分数）； 发出的内容不含姓名学号；学生代码里像指令的文字一律当作品内容；学生又交了新的只评最新的 - 提示词按教材命名习惯校准（"缩写_含义"、书上规定的控件名、界面上不用的标签保留默认名不扣分）： 教材参考答案 28/30，默认控件名且没有注释 15/30 - 评阅页：界面截图标签页、AI 建议卡片（采纳、重新评阅）、全部采纳（不覆盖老师已评的分）、评阅后又提交的提醒； 成绩表显示"AI 建议，待确认"；学生在老师确认前看不到 AI 的建议 - 规范提示移到 shared，服务端组装提示词时也用 - 配置 DEEPSEEK_API_KEY、AI_MODEL；部署说明提醒 NPM 调大请求体上限 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

|
||||
- 窗体界面：界面布局合理，美观大方，符合使用者习惯。
|
||||
- 注释书写规范：做到清晰、准确地描述内容。对于程序中复杂的部分必须有注释加以说明。注释量要适中，避免过多或过少导致阅读困难。
|
||||
- 变量命名规范：选择有意义的英文进行命名，使变量名能清楚地表达其含义。尽量少使用人名、地名和汉语拼音。应使用那些约定俗成的缩写。多个单词组成的变量名，每个单词的首字母应该大写。
|
||||
- 界面常用控件命名约定：窗体控件命名以控件名称缩写前 3 个字母开头，以具有代表含义的词来命名，其形式为：控件缩写（前 3 个字母）+ 命名（具有代表含义的单词）。
|
||||
|
||||
教材自己的写法（按教材，属于规范，不扣分）：
|
||||
- 控件名写成"缩写_含义"，缩写和含义之间用下划线，如 btn_Open、txt_SendText、lbl_port、com_port（下拉框用 com）、rb_Open（单选按钮）、ch_bodyInfrared（复选框）；设备控件 led、lamp1、alarm1 也是书上的名字。
|
||||
- 只放在界面上、代码里不用的标签和分组框，书上保留 label1、groupBox1 这类默认名字，不扣分。
|
||||
- 方法、字段、参数沿用书上的写法（如 IsOpen、AlarmOnOff(string Device, bool IsOpen)），不扣分。
|
||||
- 评分尺度：照教材参考写法完成的作业，老师评分项应得满分或接近满分；扣分针对明显偏离，如代码里用到的控件还是 button1、textBox1 这类默认名字，用拼音命名，几乎没有注释，界面控件重叠、杂乱。`

|

评分规则：
|
||||
- 只给"老师评分项"打分。程序功能是否实现已经由平台自动运行检查过，不要因为功能问题扣老师评分项的分；但从界面截图和代码能看出的界面、注释、命名问题照常评。
|
||||
- 按书上评价表的要求评分（见用户消息）。学生是中职一年级，标准宽严适中：基本做到给大部分分，明显问题再扣分。
|
||||
- 每项给 0 到满分之间的整数分，并用一句话说明依据，尽量指出具体的控件名、方法名或代码位置。
|
||||
- 评语写给学生看：2～4 句，先肯定一个具体的优点，再指出最重要的 1～2 个改进点，用学生能听懂的话；不要给出完整的答案代码，不要提到"AI"或"模型"。
|
||||
|
